Features

Vehicle Compatibility: This custom-fit ported enclosure is designed specifically to fit select 2014 and newer Chevrolet Silverado and GMC Sierra Crew Cab pickup trucks. Please enter your vehicle information to confirm fit.

Mounting Location: The enclosure mounts under the rear bench seat without taking up interior space.

Enclosure: The enclosure is made from durable MDF (Medium Density Fiberboard) that resists flexing and damps resonance. It's covered with a bedliner type material.

Terminals: The wire terminals are spring-posts (two pair) that accept pin connectors or bare wire up to 10-gauge. Inside the enclosure there are 0.205" male quick-slides (will accept 0.205" female quick slides) for both the positive and negative terminals. The wire can also be attached using the nuts holding the quick-slides in place.

Note: Speaker wire is needed to connect the terminals to the subwoofers.

Dual 12" Subwoofers: The enclosure holds two 12" subwoofers, each having its own 1.0 ft³ chamber. Once mounted, the woofers fire upward.

Mounting: No mounting hardware or speaker wire is included with the enclosure.
